Abstract

A method is provided for detecting a target impact of a munition. The method including: providing the munition with a power supply having a piezoelectric material for generating power from a vibration induced by the munition; monitoring an output from the power supply; and determining whether the output of power from the power supply has dropped below a predetermined threshold.

Claims

1. A system for use with a munition for detecting a target impact of the munition, the system comprising:

a power supply having a piezoelectric material for generating power from a vibration induced by the munition; and

a processor operatively connected to the power supply for monitoring an output from the power supply and determining whether the output of power from the power supply has dropped below a predetermined threshold.

2. The system of claim 1, wherein if the output of the power supply has dropped below the predetermined threshold, the processor further disables the round from being internally detonated.

3. A method for detecting a target impact of a munition, the method comprising:

providing the munition with a power supply having a piezoelectric material for generating power from a vibration induced by the munition;

monitoring an output from the power supply; and

determining whether the output of power from the power supply has dropped below a predetermined threshold.

4. The method of claim 3, further comprising, if the output of the power supply has dropped below the predetermined threshold, disabling the round from being internally detonated.
